Female sports injuries have been neglected by science, and few relevant studies have considered female subjects. Knee pain in female soccer players is more common than in male soccer players. The number of days of absence from training and competition has been shown to be higher in females than males. The reporting of knee pain is common in female soccer players, but whether knee pain is associated with morphological features is unclear. The Q-angle of the knee has been hypothesized to be a causal factor in knee pain. Asian females have shown higher levels of valgus than non-sporting Caucasian populations, but no data exist for female Chinese players. The aim of our study was to investigate whether there are associations between knee pain, the Q-angle of the lower limb, jump performance, play time, and perceived exertion in female Chinese collegiate soccer players. We measured the Q-angle, patellofemoral/anterior knee pain (SNAPPS questionnaire), and CMJ and SJ performance of 21 subjects (age: 20.09 ± 1.13 years, weight: 56.9 ± 6.26 kg, height: 164.24 ± 4.48 cm, and >10 years of practice) before and after a match; Borg scale and play time results were also recorded. We found that our studied group had higher Q-angles in comparison to other ethnic groups reported in the literature, as well as an association of the Q-angle with the age, height, and weight of the players; however, contrary to other studies, we did not find any association between the Q-angle and knee pain, jumps, play time, or perceived exertion. Knee pain was not associated with any of the measured variables. : Female Chinese soccer players showed higher Q-angles than players of other ethnic groups, a result that was associated with anthropometrics. The Q-angle was not found to be associated with knee pain, for which the sole determinant was body height.
女性运动损伤一直被科学界所忽视，很少有相关研究考虑到女性受试者。女性足球运动员的膝关节疼痛比男性足球运动员更为常见。研究表明，女性因伤缺训和缺赛的天数高于男性。女性足球运动员常报告膝关节疼痛，但膝关节疼痛是否与形态特征有关尚不清楚。膝关节的 Q 角被假设为膝关节疼痛的一个成因。亚洲女性的外翻角度高于非运动的白种人群，但没有中国女性足球运动员的数据。我们的研究目的是调查女性中国大学生足球运动员的膝关节疼痛、下肢 Q 角、跳跃表现、比赛时间和感知用力之间是否存在关联。我们测量了 21 名受试者（年龄：20.09 ± 1.13 岁，体重：56.9 ± 6.26 千克，身高：164.24 ± 4.48 厘米，练习时间>10 年）的 Q 角、髌股/膝关节前痛（SNAPPS 问卷）和 CMJ 和 SJ 表现，比赛前后还记录了 Borg 量表和比赛时间结果。我们发现，与文献中报道的其他种族群体相比，我们的研究组的 Q 角更高，而且 Q 角与运动员的年龄、身高和体重有关；然而，与其他研究相反，我们没有发现 Q 角与膝关节疼痛、跳跃、比赛时间或感知用力之间存在任何关联。膝关节疼痛与任何测量变量均无关。结论：中国女性足球运动员的 Q 角高于其他种族群体的运动员，这一结果与人体测量学有关。Q 角与膝关节疼痛无关，而膝关节疼痛的唯一决定因素是身高。
